PURPOSE Great advances have recently been made in treating patients with metastatic melanoma. However, existing therapies are less effective on cerebral than extracerebral metastases. This highlights the potential role of the brain environment on tumor progression and drug resistance and underlines the need for "brain-specific" therapies. We previously showed that the PI3K-AKT survival pathway ...
Cold atmospheric plasma (CAP) has attracted increasing attention due to its anti-bacterial and anti-tumor effects. Melanoma is an aggressive malignancy that increasingly common with a poor prognosis. By evaluating cell viability, detecting cells apoptosis, this study explored the differences of biological effect between melanoma human keratinocyte lines (HaCaT) treated CAP, combining reactive s...
Mutations in the NRAS oncogene are present in up to 20% of melanoma. Here, we show that interferon alpha-inducible protein 6 (IFI6) is necessary for NRASQ61K-induced transformation and melanoma growth. IFI6 was transcriptionally upregulated by NRASQ61K, and knockdown of IFI6 resulted in DNA replication stress due to dysregulated DNA replication via E2F2. This stress consequentially inhibited ce...
Melanoma is the most severe of all skin cancers as it may grow rapidly and metastasize. The application of photodynamic therapy (PDT) opens new perspectives in treatment of this cancer. Numerous studies suggest that the exposure of tumor cells to PDT can lead to cell death via two separate processes: apoptosis or necrosis. The aim of this study was to assess in vitro photodynamic therapy which ...
BACKGROUND The identification and use of novel compounds alone or in combination hold promise for the fight against NRAS mutant melanoma. MATERIAL AND METHODS We screened a kinase-specific inhibitor library through combining it with α-Mangostin in NRAS mutant melanoma cell line, and verified the enhancing effect of α-Mangostin through inhibition of the tumorigenesis pathway. RESULTS Within the ...
The PI3K/mTOR/AKT pathway is activated in most melanomas, but mTOR inhibitors used singly have limited activity against advanced melanomas. The application of nanosecond pulsed electric fields (nsPEFs) is a promising cancer therapy approach. In this study, we evaluated the synergistic anti-tumour efficacy of the mTOR inhibitor everolimus in conjunction with nsPEFs against melanoma. The combined...
Cancer including melanoma may be ''addicted" to double strand break (DSB) repair and targeting this process could sensitize them to the lethal effect of DNA damage. PARP1 exerts an important impact on DSB repair as it binds to both single- and double- strand breaks. PARP1 inhibitors might be highly effective drugs triggering synthetic lethality in patients whose tumors have germline or somatic ...
Background: Anthocyanins have been proven to affect multiple cancer-associated processes in different cancer cell lines. However, relatively few studies have investigated the effects of blueberry anthocyanins on metastatic melanoma. Thus, this study focuses on evaluating the chemopreventive potential of blueberry anthocyanins and their aglycones (anthocyanidins) in B16-F10 melanoma cells. Metho...
Considering the necessity of an individual choice of cytostatic drugs for patients with cancer disease and tumor cells' resistance to these compounds, their ability to induction of apoptosis should be investigated. The aim of this study was to determine the influence of dacarbazine (DTIC) on morphology and kinetics of proliferation of B16 and Cloudman S91 cells. It is important to determine the...
Backgrounds and Objective: Titanium dioxide (TiO2) is a potent photosensitizer in photodynamic therapy (PDT) and is activated upon ultraviolet (UV) irradiation.The aim of this study was the assessment of the effect of nitrogen –nano doped of titanium dioxide in human A-375 melanoma cancer cell line. Materials and Methods: N-TiO2 nanoparticles were prepared by mechanical mixing of urea with T...
